i nissicaxcd hy the parted thereto hy the supporting stretch ot the continuous carrier toward the scraping device, the carts being so arranged that the line ot torce et the center of gravity of the carcass is substantially perpendicular to the plane of said .supporting stretch and 'tends to maintain the relation between the carcass and said supporting stretch, Whereas the action of the scraping device located thereabove is to roll the carcass along this supporting stretch toward the direction from which the suinnorting stretch is received, the parts acting comlii'nedly to maintain the carcass-position on the 'supporting stretch closely adjacent to and in advance of the axis ot rotation ot' said scraping device, solely by the coaction between said supporting stretch ot the carrier and said rotary sc aping device located therealoove. The axes et rotation of the s raping device and ol the carcass are sulistantially parallel, while the supporting stretch of the carrier moves in a direction at substantial right angles'to said aries.

rl`he rotation of the carcass is assisted hy upwardly projectingl blades carried hy the :arrier hars c. The scraping of the heads presente dilliculties because they are smaller than the hodies ot' the cartasses-and also present resistanc, so that they are not as readily reached and acted upon hy the scrapers.

This impediment is overcome by raising the heads and hyholding them to the action ot the Scrapers. This is donc by increasingn the thickness ot thc )arrier-bars e at one end as shown at There is also a brace Q-l, shaped as shown, to permit the heads to clear it readily as they pass by. :litter they have passed, this hrace hacks up the heads and prevents them from being thrown back by the sc'apersv rThe ends ot' those scraper-arms which operate opposite the heads terminate ohliqucly and the scrapcrs carried` thereon are positioned accordingly. v

The retention of the head in this position is 'favored hy carrying the carcass in a position. whereby the hotly is in advance ot' the head. This is accomplished hy positioningsl hladcs QQ on hars c, so as to h e inclined to the direction in which the carrier mores7 as clearly shown in top View, Fig. fl.

as to adapt themselves to and t in properly with the arrangement ci: the means 'whereby the scraping device is rotated. The means to permit such elevation consisi: of a pair oie limits which at one oi their ends swing oapivots and at their other fonds carry thehearings for shaft. 16 which o seizes the scrapingdevice. 'Thesepivots s iiorined by the opposite ends ot" a shaft which finds its support in hearings provided in t ie frame-Werl; of the apparatus.

shaft serves also to actuate scraper i6 the transmission of the action bein le suitable iriachine elements.

of gear-wheels is used as shown, .ng the gear-Wheel on shaft 26 and 28 l me gear-wheel on shaft 16. The gap ed on one of? the links of the pair.

.fis noiose described, the scraping device is supported abovelthe carrier in a certain oovnellj/ lowest position which support 1s obtained lof; supporting the free end of the iinles accordingly, said means `serving also for purpose of raising the scraping-de vice when s. carcass is to he released as loefc-ve descviiied.

For such purpose We provide a hand-lever Si pivoted to a Toch-shaft 32 and extending within convenient reach of the operator,

This ioclosliait extends to the other side and ase also rigidly connected to this roch-shaft, one at cach end thereof and onef'oi? which cia3,7 simply he a continuation ofthe heed-lever ci: of both hand-levers in case ieee is one provided on each side.

-the free ends of these arms conoces them to the ends of scvapor-shaztt 16 or to limi-:s 25.

ovver is supplied to adriving pulley 35, .mounted on a sha/ft. ilfsnd transmitted by it to thevaifious parte to be operated, in any zippioved meneer. A chain-Wheel 37 on shaft 36 -operates by means ci" a chain 38, aiiothei' chainwheel 39 on shaft 26. A shaft is restated l"by nair of gear-Wheels i2 and aclieinv ieel, Wl'iich, fby means a chain s4, votates a chain-Wheel 45, 'to opeiat-e carrier C, this chain-wheel being mounted on shaft 46, which is one of the shaftssupporting one of the sets of the carrier-pulleys.

The other one of these shafts designated. at ei? carries a lchain-Wheel e8 which, 'hy means of a. chain 49 rotates a chainovheel 5l, to actoate the elevator operating shaft .Two sheaves 53 are mounted upon this elevator shaft and ropes or cables 552i, one connected to eacl1'sheave,extend therefrom 'over guidepulleys 55 and ere connected to the elevator. y

Chaiimvheel 51 is mounted loosely and rotates the elevatoi` shaft and the sheaves thereon only Wheiithe elevator is to be raised.

@secretive connection for the puipose be- .ligecl ioy intermediate' gears 29, support! pose of raising the elevator.

siveen the cliiven chais-Wheel 5l and the elevatonshaii. made a suitable clutch l5, controlled at will 'by the operator. After this connection is iliade, the elevator-ropes are caused to Winti. upon the sheaves until the elevator is raised to proper height, that is, ven with inclined bars l2, to permit the carcass to slide off as before described.

The clutch is so arranged that at that 1nonient the connection between the driven. chain-Wheel 51,' and the elevator shaft is automatically broken, causing rotation of the sheaves to cease. The elevator is now free to descend which it does by its own Weight, the elevator-ropes unvvinding from the sheaves. Weights 57, may be provided to balance the elevator so to modify the speed of this drop.'

The diameter of the sheave-Wheels is of such a size that one rotation Winds up suiiicient rope to raise the elevator to the particulai.'l

height stated after which the sheaves are permitted to rotate in reverse direction, fol lowing the pull of the descending elevator While the ropes unwind. These eects are due to the construction of the clutch, shown in, Fig. 7, and of the means for controlling it which are as follows: @ne of the complementary clutch parte shown at mounted to rotate with the loose pow-ersists of the clutch huh 5i, sliolably mounted upon the eievator shaft. 60 is a short spline or lacy also seated on the elevator shaft and between the two cliztcii-parts spring 6l., has a normal 'tendency to move the clutch-huh. into engagement with part 58 and with spline 60', hut is restrained by a latch 622 occupying a cam-groove 63, ormed by ring Se, mounted on cie clutch'- hulo and :forming a part thereof.

lf the latch is raised out of the camgroove, `the clutch-hub becomes free to :tollow the action of the spring and is moved driven chainwheel The other part coninto engagement with the live clutch-part 58 from which it derives motion. lt also engages. key 60 on the shaft and thereby transmits the derived motion. to said shaft which is now caused to rotate for the purlThe latch is operated hy a trigger 65, carried at the end of ali-operating arm 68. 'll/Ianipulation is jv a rod 6'? connected tc another arm 68. Both arms 66 and 68 arc mounted upon a rocisliaft 69. When clutch-huh is shifted yhach again ley the released latch, it

loses connection vwith the live clutch part and also with key 60 so that shaft 52 loe comes free to revolve in opposite direction to permit` umvinding of the elevator ropes.

lt will 'he observed that in this apparatus, the scraping edges move over the skin with a protracted contact and. remove the hair with a true scraping action which in its eli'ect does lnot extend :belowv tice shia, in

rcmitradistinction to the ponnding the scope oi' the appended claims,

action oi devices 0 the beater type, which rely :tor removal o' the hair upon the .ltact by a blovvr :troni a long beater arno, largely sustained by the effects oi centrifugal force.

This action is conside 'ed objc,cionable inas-` innch as it has a tendency to broch up the ineat libere, separates the lean from the tat and renders the meat soit and inushj,T b v meshing and 'breaking down its cells.

lt is obvious that changes in structures may be made in our improved device, Within without departing troni the spirit of our invention.
